Materials Laboratory Technician — Cary, NC
Laboratory technicians turn field samples into the numbers projects run on: Proctor curves, sieve analyses, Atterberg limits, moisture contents, and compressive strength breaks. You will work inside a documented AASHTO R18 quality system with calibrated equipment and real accountability for every result that leaves the lab.
This is a project-site position supporting programs in and around Cary, North Carolina, staffed through the Raleigh, NC regional hub on a project basis with travel as assigned.
Field days near Cary mean Piedmont saprolite, micaceous silt discipline, and boom-metro concrete, with variety that builds a career, not a resume.
What you'll do
- Perform ASTM D698, D1557, D2216, D4318, C136, and C39 testing
- Maintain calibration, standardization, and quality records
- Log samples and preserve chain of custody
- Break cylinders and report strength results same day
- Support proficiency sample programs and accreditation assessments
What we're looking for
- Careful hands, clean documentation habits, mechanical aptitude
- Prior lab or CMT experience a plus, not required — we train
- Comfortable with repetitive precision work done right every time
What a week in this job looks like
Field samples arrive in waves: bags of borrow for Proctors, buckets of base for gradations, jars for Atterberg limits, cylinders for the break schedule. Your week is the disciplined conversion of that material into numbers projects run on. Ovens loaded and logged, sieve stacks shaken to constant result, limits rolled to an eighth-inch thread, cylinders capped square and broken on schedule with the fracture photographed.
It is precision work with a rhythm to it. People who like doing things exactly right, every time, with the radio on, tend to love this room.
Break days have their own cadence: cylinders pulled from the tank on their exact ages, ends checked, machine loaded at the standard rate, results in the system before lunch so a contractor somewhere can strip forms. On heavy weeks you will break dozens, and every one of them is a promise the field made that the laboratory keeps.
Certifications, training, and where this leads
We train you method by method inside a laboratory that answers to AASHTO re:source and CCRL assessors, which means your training is not tribal knowledge, it is a documented competency record with your name on it. ACI laboratory certifications and NICET construction materials testing levels follow as you build scope, on the company's dime.
Laboratory technicians who master the soils bench and the concrete bench become the people who train others, run proficiency programs, and step into laboratory supervision. It is also the strongest technical foundation in the industry for anyone who later wants field, engineering, or management tracks.
Pay, schedule, and travel
Pay runs $25 to $35 per hour with overtime during heavy testing seasons. The laboratory runs on a steadier clock than the field, mostly daytime hours with predictable surges when big earthwork programs or break schedules stack up.
This is a facility-based role at the laboratory serving your region's work, with occasional field sampling support when the schedule calls for extra hands.
Safety, quality, and the standards we work under
The laboratory operates under a written quality management system built to AASHTO R18: calibrated equipment on documented schedules, technician competency records, proficiency samples, and internal audits that find problems before an assessor does. You will be trained on chemical and equipment safety for every method you touch.
Accuracy here is not a slogan. A wrong Proctor curve fails good fill or passes bad fill across an entire project, and the system exists so that never happens quietly.
How hiring works, and our commitment
Apply with whatever shows us how you work: lab experience, QC experience, or any history of careful, repetitive precision done right. Expect a call within days, a walk-through of the bench work, and a clear offer. The role requires the ability to lift sample containers, stand for extended bench work, and complete pre-employment screening consistent with laboratory and jobsite requirements.
We are an equal opportunity employer and consider every applicant without regard to race, color, religion, national origin, age, sex, sexual orientation, gender identity, disability, or veteran status.

FAQ
Working in Cary — common questions
Is the Materials Laboratory Technician position in Cary an office job or a field job?
Laboratory-based. Laboratory technician roles work in the Sugar Land, Texas laboratory or a project mobile laboratory; a Cary listing means the project served is in the Cary, NC area.
Which hub covers Cary?
The Raleigh, NC regional hub, about 8 miles away. Work in Cary is staffed on a project basis through that hub.
Do I need to relocate to Cary?
Not necessarily. Project-site positions are staffed with travel and per diem as assigned; candidates already living near Cary are preferred when a project starts there.
What certifications does a Materials Laboratory Technician in Cary need?
None to start; NICET Construction Materials Testing (Soils, Concrete) certification is the path, earned on the job and paid for by the company. Candidates already holding NICET, ACI Concrete Strength Testing Technician, or ACI Aggregate Testing Technician certifications start higher in the range.
What tests will I run on Cary projects?
Compressive strength (ASTM C39), Proctor curves (ASTM D698 and D1557), sieve analysis (ASTM C136 and D6913), Atterberg limits (ASTM D4318), moisture content (ASTM D2216), and specific gravity (ASTM C127, C128) on samples from the projects the hub serves.
What should I include in my application?
Years of experience, any certifications (ACI, NICET, ICC, nuclear gauge), and either a resume file or a short work history in the form. Applications without certifications are welcome for entry-level roles.
